چکیده
Poly(vinylidene fluoride-co-trifluoroethylene) (P(VDF-co-TrFE)) is an electroactive polymer with growing interest for applications in biomedical materials and flexible electronics. In this study, a solvent-free additive manufacturing technique called melt electrowriting (MEW) has been utilized to fabricate well-defined microperiodic structures of the copolymer (P(VDF-co-TrFE)). MEW highly viscous was initiated using heated collector at temperatures above 120 °C required remarkably slow speeds below 100 mm min−1. The fiber surface morphology affected by speed increase β-phase observed scaffolds compared unprocessed powder. Videography shows vibrations P(VDF-co-TrFE) jet previously unseen during MEW, probably due repeated charge buildup discharge. Furthermore, piezo-force microscopy measurements demonstrated electromechanical response MEW-fabricated fibers. This research therefore achieves electrohydrodynamic processing fibers micrometer resolution into defined important polymer. © 2021 Authors.

The absorption of water in Langmuir–Blodgett fi lms of ferroelectric copolymers of polyvinylidene fl uoride with trifl uoroethylene is shown to depend upon the fi lm thickness. This water absorption can have a profound effect on the dielectric properties of the copolymer fi lms.

Oriented polyvinylidene fluoride-trifluoroethylene (P(VDF-TrFE)) films by Langmuir-Blodgett deposition: a synchrotron X-ray diffraction study.
Langmuir-Blodgett films of polyvinylidene fluoride trifluoroethylene - P(VDF-TrFE)-copolymers possess substantially improved electrocaloric and pyroelectric properties, when compared with conventionally spin-cast films. In order to rationalize this, we prepared single-layered films of P(VDF-TrFE) (70 : 30) using both deposition techniques. Grazing incidence wide-angle X-ray scattering (GIWAXS),...
متن کاملUniversal Ferroelectric Switching Dynamics of Vinylidene Fluoride-trifluoroethylene Copolymer Films
In this work, switching dynamics of poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] copolymer films are investigated over unprecedentedly wide ranges of temperature and electric field. Remarkably, domain switching of copolymer films obeys well the classical domain nucleation and growth model although the origin of ferroelectricity in organic ferroelectric materials inherently differs ...
متن کاملMagnetoelectric CoFe2O4/polyvinylidene fluoride electrospun nanofibres.
Magnetoelectric 0-1 composites comprising CoFe2O4 (CFO) nanoparticles in a polyvinylidene fluoride (PVDF) polymer-fibre matrix have been prepared by electrospinning. The average diameter of the electrospun composite fibres is ∼325 nm, independent of the nanoparticle content, and the amount of the crystalline polar β phase is strongly enhanced when compared to pure PVDF polymer fibres. The piezo...
